SPECIFICATION forming part of Letters Patent No. 449,029, dated March21, 1891.

Application filed am 3, 1890.

To all whom it may concern:

Be it known that I, JUsrUs BEISHEIM, of Rochester, in the county ofMonroe and State of New York, have invented certain new and usefulImprovements in Grates; and I do hereby declare the following to beafull, clear, and exact description of the same, reference being had tothe accompanying drawings, forming a part of this specification, and tothe letters of reference marked thereon.

My invention relates to improvements in grates particularly for use instoves, and has for its objects to provide a grate by which not only canthe whole of the bed of fuel loe agitated or shaken as much as desired,but a portion or the whole thereof can be cut out or dumped into theash-pit below; and also to provide a grate simple and cheap inconstruction.

To these ends the invention consists in certain novelties ofconstruction and combinations of parts, all aswillbe hereinafterfullydescribed, and the novel features pointed out in the claims at theend of this specification.

In the drawings, Figure 1 is a plan view of a grate constructed inaccordance with my invention; Fig. 2, a longitudinal sectional viewthereof on the line as w of Fig. 1; Fig. 3, a crosssectional view on theline y y of Fig. 1; Fig. 4., a top plan view of the end of the sections,with the covering plate removed showing the actuating devices; Fig. 5, asection on the line a a of Fig. 3; Fig. 6, a section of a modificati on;Fig. 7, a side view of the cam or disk on the rotary section.

Similar letters of reference in the several figures denote similarparts.

The letter A indicates the stove-casing or the frame supporting thegrate, having near opposite ends plates B resting on lugs orabutments-such as a a on frame Aand provided with deflecting flanges bat the lower portions, as shown.

In the upper portions of plates B are provided apertures or recesses inwhich the projections or arms old on the side sections D of the gratehave their bearings, while slightly below them are provided apertures inwhich the journals 0 of the central grate-section C have their bearings.The grate-sections D are arranged on opposite sides of the fire-pot andare provided with a series of inclined fin- Serial No. 366,945. (Nomodel.)

gers 01, arranged to project in close proximity to the ends of cuttingfingers or projections a, formed on the central section 0, arrangedslightly below. The central section 0, which I term the rotary section,is, as stated, journaled in the plates B, and is adapted to be rotatedor oscillated by a suitable handle applied to its angular end, and nearsaid end, but inside plate B, is a disk or cam E, dished or hollowedslightly on its inner side and provided with a notch e in its underside, as shown, said cam projecting between two of the end fingers f fof the sections D, so that as the section 0 is oscillated in itsbearings the parts D will be reciprocated back and forth alternately,causing a thorough agitation of the fire-bed to the extreme edges andcausing the fine ashes and clinkers to fall through the openings betweenthe fingers and the larger portions to slide down upon section 0, whenthey may be removed by a full rotation of the latter, serving to cut outthe central portion of the bed of fuel and dump it into the ashpit.

Near the upper portions of the plate B are arranged deflecting flangesG, which project.

over the ends of the sections D and prevent ashes or coals from lodgingbetween them and the plates, thereby interfering with the action of thegrate. By making theinner side of the disk E hollowed, as shown, andcurving inward the fingers f, not only will the lodgment of ashes andcoals be prevent-ed,but the binding caused by the twisting or lateralmovement of the sections D when reciprocated will be prevented and saidsections caused to move in right lines Without binding in theirbearings.

H indicates a plate operating as a cover for the operating portions ofthe grate and also serving, if desired, as a support for the firebrickor lining H of the fire-pot, said plate being provided with flanges h atthe ends cooperating with plates B and at one end with the covering ordeflecting flange gfor protecting the cam or disk E. This latter flangemight be formed on one of the plates B, if desired; but I prefer thearrangement shown. Plate H is provided at one side with lugs h h, whichengage recesses formed in the main frame, so that when in position itwill be locked by the fire-pot lining H; but when the latter is removedsaid plate may be turned up, as indicated by the.dotted line, Fig. 4,and the lugs disengaged, as will be understood. \\''hen the plate 11 isremoved, one or both of the plates B can be drawn vertically and thegrate-sections, or any of them, removed, the fingersfsliding out throughthe slit 6 in the cam, which is turned, so as to cause them to registerand new sections inserted when desired or necessary.

Instead of employing two reciprocating side sections D, as described,one only could be employed, the arrangement being substantially as inFig. 6, the grate P at the forward portion being stationary, as in theordinary cooking-stove grates now in use.

The operation of the various parts will be understood from theforegoing, and it will be seen that all parts of the fire can bethoroughly agitated and all or portions of it dumped or cut out whendesired without opening the stove and using a poker to dislodge thoseportions at the edges of the grate.

Various modifications will suggest themselves to those skilled in theart, and I therefore do not desire to be confined to precisely theconstruction herein shown.

I claim as my invention- 1. In a grate, the combination, with thecentral rotary oscillatory section having the cam or disk thereon, ofthe two side sections reciprocating lengthwise of and relative to thecentral section and actuated by the cam thereon, substantially asdescribed.

2. In a grate, the combination, with the two side sections arranged toslide in straight bearings, of the central rotary oscillatory sectionhaving the cutting fingers or edges and the cam or disk thereonco-operating with the side sections and causing their reciprocation,substantially as described.

3. In a grate, the combination, with the two side sections arranged toslide in straight bearings and having the fingers thereon, of thecentral rotary oscillatory section having the cam or disk and thecutting teeth or edges, substantially as described.

-l. In a grate, the combination, with a rotary oscillatory sectionhaving a cam or disk thereon, of a reciprocatory section arranged at theside of said rotary section and co-operating with the cam thereon,whereby the rotary movement of the first mentioned section will cause areciprocation of the latter relative to it, substantially as described.

5. In a grate, the combination, with aninclinedlongitudinally-recitwocatory grate-section, of a rotaryoscillatory grate-section having cutting teeth or edges arranged belowsaid first-mentioned section and having a cam or disk co-operatingtherewith for causing its reciprocation when the rotary section ismoved, substantially as described.

6. In a grate, the combination, with a longitudinally-reciprocatorygrate-section having curved fingers thereon, of a rotary oscillatorygrate-section having a dished or hollowed cam or disk thereonco-operating with the curved fingers on the first-mentioned section,substantially as described.

7. In a grate, the combination, with the reciprocatory grate-sectionshaving the end extensions, the plates in which they slide having theflanges for protecting said ends, of the central rotary section havingthe cam or disk thereon co-operating with and operating thereciprocatory sections, and the coveringplate having the flange forprotecting said cam, substantially as described.

8. In a grate, the combination, with the main frame or casing, theplates B, and the reciprocatory sections having their bearings therein,of the central rotary section having the cam or disk co-operating withthe other grate-sections journaled in said plates, and the cover-platecooperating with the plates B, substantially as described.

9. In a grate, the combination, with a reciprocating grate-sectionhaving the fingers, of the central rotary section having the cam or diskhaving the slot e therein and co-oper ating with and reciprocating thefirst-mentioned section, substantially as described.

10. In a grate, the combination of the main frame, the Vertical plates,the grate-sections having bearings therein, and the cover-plateco-operating with the vertical plates and having the engaging lugs onone side co-oporating with the main frame, substantially as described.
